Title: Oscillating flat screen classifier - for granular material with tension belt drive
Inventor: KUEPER WALTER DIPL KFM
IPC: B07B1/46
Filed: 1972-04-13
Abstract: Flat perforated screen for de-watering and classification of granular material, is of rubber or rubber-like synthetic material with a soft, wear resistant material on the top layer and a support layer on the underside.

Patent DE-2333684-A1 (DE)
Title: Stepwise drive for roller transported articles - has two speed gear box driven from machine tool with electromagnetic gear engagement
Inventor: HUEBNER WOLFGANG
IPC: B21D43/09
Filed: 1973-07-03
Abstract: The drive from the machine tool is transmitted by a connecting rod to a crank mounted on a free wheel on the input shaft of the gearbox. The drive is transmitted by either of two gears to a second shaft. The gear can be selected by energising electro-magnetic clutches mounted on the shaft. The drive may be transmitted to the conveyor rollers either directly from the second shaft or through a gear train driving either of the shafts or fitted with Hooks couplings. A choice of conveyor speed is thus provided.
Patent DE-2333885-A1 (DE)
Title: Falling film evaporator with pulsed feed - having balls over vertical tubes pulsed by vibrator
Inventor: TROSCHENKIN BORIS ALEXANDROWIT
IPC: B01D1/06
Filed: 1973-07-03
Abstract: Falling thin film evaporator has vertical tube bundle with liquor feed chamber and inlet branch. The inlets to the tubes have restrictors which form annular slots to give the film down the tubes. The distributor chamber has a pulsator fitted which can cause vertical oscillations in the restrictors, their movement being limited by a horizontal limit plate. The evaporator can be used for all purposes of evaporation - concentrating solns., foodstuffs, or recovering potable water from saline. Existing designs use fixed restrictors with constant apertures. If the liquid contains undissolved solids, these tend to foul and block, but vibration keeps the slots clear. More uniform distribution is given and the film is more agitated and thus gives better heat transfer. Down time is reduced by the self cleaning action.
Patent DE-2335196-A1 (DE)
Title: Isolating valve with two separable housings - enables radiator to be removed without dismantling associated water heating pipes
Inventor: SCHULZ-PRUSS MARTIN
IPC: F16K43/00
Filed: 1973-07-11
Abstract: A threaded sleeve causes a valve seat on the spindle of the valve to strike against a closing mechanism in another valve housing, downstream from the first. The two housings are joined end to end by a screw cap which unscrews in the direction of the flow of water to separate the housings. It is preferred that the activating handle should take the form of a sleeve screwed on to the first housing and overlapping the capscrew at one end. The isolating valve disc is spring loaded, and radiator may be individually removed and replaced into system without danger of causing air locks.

Title: Folding frame for tyre snow grip - which is dropped over wheel and tightened without having to move wheel
Inventor: HAAGA WALTER
IPC: B60C27/02
Filed: 1973-09-22
Abstract: A framework of hinged rods with open hoops at the free ends is linked to a tensioning chain or cable. When folded flat it can be placed over the wheel and gradually unfolded, to bring the hoops into contact with the tyre tread and to tension the chain or cable so that finally the frame is rigidly secured on the tyre. The hoop ends can be partly joined by chains for extra grip and stability. The frame is rapidly fitted by the layman without having to move the wheel, and without special tools. The cable is in a star shape meeting at the points of the framework and tensioning it when fitted.
Patent DE-2359837-A1 (DE)
Title: Consumption meter for flowing media - has mechanism operated by medium pressure and based on dual chamber system
Inventor: MOELLING GUENTHER
IPC: G01F3/20
Filed: 1973-11-30
Abstract: The to-and-fro movement of a diaphragm is converted by a lever system into a rotary motion for a counter drive. The diaphragm is connected by two discs to a guiding element in the case, perpendicular to the diaphragm, so that it is stabilised. The stroke of a transmission element, and thus the point of engagement of the pawls, and the stroke of the swinging lever operating the switching mechanism are controlled by the displacement of a lever pivot. This displacement is controlled by a screw accessible from outside thus removing the normal intricate and protracted use of changeable wheels.

Patients whose pupils are wide apart or who have large noses thus do not any more come into contact with the camera objective.
Patent DE-2417552-A1 (DE)
Title: Loom weft yarn feed - has store drum fitted with webs to support stored yarn windings under constant tension
IPC: B65H51/22
Filed: 1974-04-10
Abstract: An appts. is claimed for the continuous feed of a weft yarn to a loom, with a winding unit to build up stored coils of the yarn which travel back over the winding drum, where a number of webs are located round the winding drum to range into the zone between the chamfered end of the unit and the cylindrical drum zone. The system converts the yarn windings into a polygonal cross-section, allowing a constant tension and control to be applied to yarns of all types, and without the yarn feed unit requiring any mechanical advance mechanism.

Title: Playback unit with pick-up arm control disc - disc driven by electric motor independent of turntable drive motor
Inventor: STROBEL ROLF
IPC: G11B3/08
Filed: 1974-05-08
Abstract: The control disc has a single control track and there are means to drive the control disc in different directions of rotation. The control of the movement of the pick-up arm has assigned to it a rotation of the control disc in one direction for the starting process and a rotation in the other direction for the stopping process. One full revolution of the control disc in one direction can be assigned for stopping and two full or part revolutions with opposite directions of rotation for starting and record changing. The first of the two revolutions is in the same direction as rotation of the control disc in stopping.

Title: Tank for cryogenic substances - esp. for transport of liquefied natural gas at low press.
Inventor: ITO KENKICHI
IPC: F17C3/06
Filed: 1974-07-20
Abstract: The housing of a tank for cryogenic substances is internally lined with at least one layer of a thermoplastic material such as polyethylene or co-polymer in foamed form, whose freezing temp. (second transitional point) is slightly higher than the temp. of the substance in the tank. The slastic is installed in such a way as to prevent or limit its free thermal contraction. The low thermal contraction of the insulation and the corresp. low internal stresses enable it to be used to produce comparatively inexpensive vessels for transport.

Title: IC engine exhaust gas reactor - mixes exhaust from two cylinders before admission to reaction chamber
Inventor: MAURER HELMUT
IPC: F01N3/26
Filed: 1974-07-30
Abstract: A multicylinder engine has one reactor for each pair of cylinders, the discharge from all reactors joining into a common silencer and exhaust. Each reactor has a cylindrical casing (11) with external insulation (12) and two connections (2, 3) perpendicular to its axis for the cylinder exhausts. The connections open into a mixing tube (13) which is concentric within the reactor body, one connection coming in at each end of the mixing tube. The tube has holes (19) in its centre through which the mixed gases escape into the combustion tube (17) which surrounds the mixing tube coaxially. This averages out differences in temperature and composition between different cylinders during the course of a revolution to improve reactor efficiency.

Title: Valve camshaft for O.H.V. I.C. engine - has one cam for inlet and exhaust valves for each cylinder
Inventor: OELMANN ERICH
IPC: F01L1/053
Filed: 1974-09-12
Abstract: Each cylinder of the engine has an inlet valve (4) and an exhaust valve (3) inclined at an angle to each other. An overhead camshaft (1) runs horizontally above the top of the cylinder head with its axis on the extension of the centre line of the exhaust valve. The camshaft carries only one cam (2) per cylinder. This acts directly on the tappet of the exhaust valve and operates the inlet valve through a rocker arm (5) pivoted above the top of the cylinder head. The rocker arm is bent so that the cam follower is at an angle and position relative to the exhaust valve tappet such that the required relative timing of the two valves is obtained.
